Will this phone work on Verizon network?
I regret to infrom you that a GSM unlocked phone will not work with Verizon as Verison uses a CDMA enabled Network.
Will this phone work with AT&T?
A phone listed as GSM unlocked will work on any GSM network, including AT&T
I live in Mexico will the unlocked I-phone 4S mentioned for $79.99 work here thank you
As long as you're using a GSM network in Mexico the GSM unlocked device will work.
How many days is ''standard shipping'', because I need to know when my order will arrive?
That depends on where you're located, as we are in Newport Beach California.
